IMPROVEMENT IN GATES.

The Schedule referred to in these Letters Patent and making parl: of thesame.

To ZZ whomY it may concern Be it known that I, ALBERT J son DIMIcK, ofBerlinville, in the county of Erie and State of Ohio, have invented anew and useful Improvement in Farm- Gates; and I do hereby declare thefollowing to be a full, clear, and exact description thereof',sutijcient to enable those skilled in the art to which my invention arecapable of a sliding movement backward and forward, as well as aswinging movement on an axis; and

lt consists inthe application to the lower end of the axis of the crane,(which forms part of the gate,) ofy a bearing fitted to slide verticallyon guide-posts arranged diagonally to each other, the upper portion ofthe axis being rounded and passing through a stationary block attachedto the top of the guide-posts, so that byinserting a pin in a hole inthe said rounded part, above the upper bearing, the crane, (and, withit, the gate,) may be retained in an elevated position above the. groundto clear snow-drifts and to leave a passage-way beneath the gate, ashereinafter described, while the swinging and sliding movements of thegate remain unchanged and unimpeded.

In the drawing- A, B, and C represent, respectively, the standard, arm,and brace, composing the swinging crane.

'lhe arm of the crane is provided with an attachment, D, in which issupported a pulley, E, and F is a pulley situated at the other end ofthe arm On these pulleys the gate It slides back and forth. These parts,being old, will require -no further description here.

As the present invention consists in the means for raising the crane andgate and retaining them in an elevated position,`so as to swing overdeep snow and al so'to allow ofthe passage of sheep-or hogs into otherfields, I will now describe those parts in detail.

llo the lower part of the standard or axis A is swiveled a foot-piece orlower bea-ring, K.

This piece slides vertically between and upon the posts O 0, which arearranged diagonally to each other, as clearly shown, the ends'of thepiece K being notched to receive or engage the guiding-posts O.

To the top of the posts O O is secured a stationary piece, N, throughwhich the upper part of the standard of the crane passes.

The part ofthe standard which passes through the piece N is rounded, asshown at L, so as to turn freely in its bearing. i l

M represents apin, which, being passed through'a h ole in the upper partof the standard A, supports the crane land gate at any desiredelevation.

G represents the foot of the standard, passing through and turning inthe foot-piece. K.

I do not claim a gate sliding backward and forward in a swinging crane,as this is not ot my invention; neither do I claim elevating andsupporting the gate, broadly, as my' invention consistsonly in theadaptation by which I have applied the principle to this class of gates.

XVhat I claim as new, and desire to secure by Letters Patent, is-.

The combination of 4the slidingbearing K, guided between and upon' thediagonally-arranged posts O O, the stationary bearing N, atxed to saidposts, and the pin inserted in ahole iu the rounded part L Qt' the axisof the crane, when all saidY parts are constructed and arranged asherein set forth.
